Patent number: 8702785Abstract: A prosthetic stent graft for the treatment of AAA includes a plurality of graft legs, each secured in a deployed position by a sealing gasket within a stent segment of the sealing gasket and to one side of a framing bracket. The framing bracket traverses the diameter of the stent segment and extends axially away, dividing the first stent segment into two portions, each portion for receiving a graft leg of the stent graft. The sealing gasket can include a stabilizer having a second generally cylindrical stent segment, and an extension bracket traversing the diameter of the second stent segment and extending away from the second stent segment. The extension bracket and the first bracket are connected with one another at a mutual generally central position.Type: GrantFiled: December 30, 2005Date of Patent: April 22, 2014Inventors: Isaac John Khan, David C. Majercak, Jin S. Park, Diana M. Sanchez

Patent number: 8372141Abstract: A stent is provided for an endoprosthesis having a main body portion and two leg portions, particularly suitable for treatment of an abdominal aortic aneurism. The stent includes barbs that are twisted and shaped set to point radially outward. Each barb, as formed, points substantially perpendicular relative to the longitudinal axis of the stent, even when in a non-deployed configuration. The motion to move the barb into a deployed configuration for gripping tissue is a twisting motion which moves the barb from being substantially aligned with the circumference of the stent to extending radially outwards from the stent.Type: GrantFiled: August 19, 2010Date of Patent: February 12, 2013Inventors: David C. Majercak, Jin S. Park

Patent number: 8226703Abstract: An aneurysmal repair system that utilizes a modified intraluminal scaffold apex and a delta stitch suture to secure graft material to the scaffold structure allows for no relative movement between the graft material and the scaffold structure. The absence of relative movement reduces the wear on the graft material.Type: GrantFiled: February 29, 2008Date of Patent: July 24, 2012Inventors: Salvatore G. Caldarise, James Fleming, David C.

Patent number: 8202310Abstract: An abdominal aortic aneurysm repair device having an access port may be utilized to percutaneously access the aneurismal sac without disturbing the repair. The access port has a self-sealing member for maintaining the port in the normally closed position. The insertion of a percutaneous device into the port opens the port.Type: GrantFiled: July 14, 2006Date of Patent: June 19, 2012Inventors: David C. Majercak, Matthew E. Krever, I.

Patent number: 8163006Abstract: An abdominal aortic aneurysm endoprosthesis having a reduced profile for percutaneous delivery of the endoprosthesis. The endoprosthesis provides a cranial section supported by a stent, and a bifurcated caudal section having at least two legs each of which are supported by individual stents. The individual stents of each leg of the caudal section are staggered so as not to line up with one another. Altering the lengths of the legs permits nesting of the endoprosthesis. Optimizing the expansion ratio and radial strength of the endoprosthesis is achieved by altering the dimensions of the starting material from which the stent segments are fabricated, by altering the final austentite temperature of the starting materials, or by changing the structural configuration of the stent segments. A graft material is attached to at least a portion of the cranial section and to all of the caudal section of the endoprosthesis.Type: GrantFiled: July 27, 2005Date of Patent: April 24, 2012Inventors: Frederick Feller, David C. Majercak, Jin S. Park

Patent number: 7918884Abstract: A stent includes a lattice defining a substantially cylindrical configuration having a proximal end portion and a distal end portion, and a middle portion between the proximal end and the distal end. The lattice being moveable from a crimped state to an expanded state, and a plurality of adjacent hoops. Each hoop has a plurality of adjacent loops. Additionally, the stent further includes a plurality of bridges connecting adjacent hoops and a plurality of extensions on the lattice. Each of the hoops and bridges define a cell. The proximal end portion and the distal end portion of the lattice have at least one cell respectively and the middle portion of the lattice has at least one cell. The plurality of extensions are on the middle portion of the lattice. The plurality of extensions are cantilevered projections from the bridges and/or hoops of the lattice.Type: GrantFiled: June 8, 2004Date of Patent: April 5, 2011Assignee: Cordis CorporationInventors: David C.
